Hardware

There are three items of hardware that we use.

• The Illusionist Desk [See section title 'Desk Hardware']
• The MCC (Motor Control Cabinet)
• 4x BigTow200 Motors

All of this hardware is designed and built by Stage Technologies.

Desk Hardware

The desk we use for the Automated Flying system within the Academy is the Illusionist Desk.

The controls for the desk

• A flat panel display screen
• 58 command keys on the right hand side of the console
• A compact external keyboard
• 3 E-Belt playbacks (far left red,then blue and yellow) each with go/stop and select keys
• An emergency stop button
• A touch pad with left and right mouse buttons
• A single adjustable desk light
• A writeable CD Rom drive
• There is a mountable rack
• A single deadman's handle situated below the playbacks

With the deadman's handle it is essential it is pressed and held down before amove and kept pressed down for the duration of the move.

Constraints imposed by the hardware

• Not designed to be portable
• Does not have a touch screen
• There is no duplicated computer hardware
• The illusionist only has three playbacks so it would be impossible to create a cue that would

require five playbacks.

Changing a speed

Playback works in two different ways, Joystick and Speed. The E-belt on our board changes both the direction and speed. In speed mode the E-belt is used to alter the speed of the assigned axes. The playback will be set at 100% by default, meaning the axes will move at their plotted speeds. The plotted speeds can be altered, using the E-belt can slow or spees up the move. The system can determain that no axes will exceed its maximum speed. So as long as the plooted speed of the axes on the playback is not more than 50% of the allowed maximum the speed can be increased to 200%.

Start/Stop Button

The button below each playback is a mulit-functional button for both start and stop. The button will read the action that is taking place, i.e if the button states 'stop' all axes will be stopped on that playback.

NB The dead mans handle must be pressed to start any movements.

Icons for Start/Stop Button

GO - Pressing this will start any movement

STOP - Pressing this will stop any movement

TIMER ICON - This indicates that the playback is busy and the operator must wiat till the operation is complete

Select Button

The button above the each playback is the select button. Only one playback is active at one time, so when a command is entered it will be applied to all axes on the selected playback.

NB When the playback is selected the select button is amber and blue when inactive.

Icons for Select Button

Tick - This means the playback is selected

Cross - This means the playback is not in use

Command Keys

Axis is a resource command. When pressing the axes key it allows the operator to add or remove a selected axes from a playback or to apply specific properties to the selected axes (accel,decel,speed). The axis key must be illuminated amber when wanting to reference.

Group is a resource command. This key allows you to load groups onto a playback, or specify particular properties (accel,decel,speed). The group key must be illuminated amber before referencing.

Action is a resource command.This key is used to load an action onto a selected playback. When loaded to a playback it overrides any exsisting instructions on the selected playback with action.

VCAtion is a resource command. When the action key is pressed twice this allows the operator to load a previous Visual Creator Acton on the selected playback. Loading a recorded VCAction overrides any existing instructions on the selected playback with VCAction.

State is a resource command. This key loads a state from a current show. In performance mode this is the default command.

Macro is a resource command. Pressing this key allows the operator to load a specific macro onto a selected playback. The macro will be executed when the playbacks 'Go' button is pressed.

Define, Rig and Reference Scenery

Once you have physically rigged your scenery you will need to soft rig the scenery on the desk. The process for doing that is:

[SHOW] [001] [RECORD]

[RIG]

select "Define Scenery" Tab

Select the Axis/Axises you want to rig (using [Ctrl] key on keyboard to select more than one)

Select whether it is a "Single Axis" or "Multi Axis"

• If you select "Multi Axis" you will be given the option of what kind of group to make it: Safe, Locked etc. You will also be asked to give it a "Group Number" and "Master Axis". The Master Axis is the Axis the height for your reference possition is taken from, it is used most effectivly on groups where the axis' are at different heights eg. for a slanting roof.

Select "Rig/Derig Scenery" Tab

Select Axis, Click "Rig" then "Reference". 99% of the time you will reference to 0m

Referencing

The act of referencing is done to give a point of reference to the size of the piece of scenery being flown. A reference point would normally be set with the scenery just touching the deck. You would then plot your deads. Should the piece of scenery change size - a drop stretching, a doorway shortened/extended instead of changing each dead individually you can change the reference point and all the deads will automatically be adjusted. Very useful if you have an indecisive designer or multiple deads.

N/B You can only change your reference point if you have manualy set your reference point. If you have auto referenced you can not change your reference point.

Control of Axis

Each axis can be moved easily without having to group or reference them first. To move a single axis-

1. select the playback you want to use by pressing the button above it, the yellow tick should appear
2. Select which axis you wish to move- [Axis] (1)
3. Enter the height to which you want the axis to move- [pos] [5000]
4. If necessary select the time in which you want the move to be completed in- [time] [10]
5. Hold down the DMH
6. Press the button below your selected playback so that the (go) message appears

• The speed at which the axis is travelling can be increased or decreased by using the E belt
• The DMH must be held down until the move is completed
• In order to stop the move before it is completed press the button below the playback so that it shows the (stop) message
• In order to move more than one axis, at point 2 enter- [Axis] (1) [->] (4)
• To clear the playback and begin a new command- [enter] [enter]

Triggers

A Trigger is used to start an action on another axis when one axis reaches a certain speed or position. A Trigger can be set using the [MORE] menu.

A Trigger can only be set when the triggered axis's and the triggering axis are set on different play backs.
